Classic [[trigeminal neuralgia]] (TN) involves sharp, shooting pain in any [[trigeminal nerve]] distribution, whereas atypical TN presents with constant aching, numbness or burning that can appear with classic features, leading to a mixed presentation or [[mixed trigeminal neuralgia]].

The [[Visual Analog Scale]] (VAS) and the [[Barrow Neurological Institute Pain Scale]] (BNI-PS) are 2 of the most frequently employed patient-reported outcome (PRO) tools used by clinicians to rate pain for patients with [[trigeminal neuralgia]] (TN).
